The Cicada's Song Episode 5

Yu Song Fan receives news that Yang Cheng—the man who had murdered his wife and child years ago—was critically ill. Upon visiting the hospital, he learned a shocking fact: they shared a grandson, Yang Awu. The realization that he might have a biological grandson brought a ray of light into Yu Song Fan’s otherwise bleak and despondent life. Meanwhile, Ding Ning became lost in a dense, primeval forest; she was found by an eight-year-old boy—a veritable "Tarzan"—who turned out to be none other than Yang A Wu. The person who had quietly raised Yu Song Fan’s grandson for nine years was Zhao Yi Jie—the very criminal defense lawyer who had represented the perpetrator in the case involving the rape of Yu Song Fan’s son.
